RECHARGE' The term 'RECHARGE, SAY' can be solved by the four-letter word 'REST'. Resting is an important part of maintaining physical and mental health. It is a period of time when one takes a break from activities and allows their body and mind to relax and recover. This can be done through activities such as sleeping, meditation, or simply taking a break from work. Recharging can help to reduce stress, improve concentration, and increase productivity.
